Well, I've really done my due diligence in trying to figure out how to contribute software: I've looked in Contribute, found the Contact Us link for submitting software, learned that there's no email contact at the moment and I should look at the forums.
There I found no dedicated forum or thread for people who want to contribute software, so I have read this and other threads and have concluded there's no obvious place to do so. I understand the admins are busy and fully respect that, but as a potential contributor it feels a bit difficult to contribute! What is the next step? How do I contribute software?
